  <h3>NetBSD/pmax:</h3>
- <p>
+ <p><a href="http://www.netbsd.org/ports/pmax/">NetBSD/pmax</a> was the
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+ first guest OS that could be
+ <a href="http://mail-index.netbsd.org/port-pmax/2004/04/18/0000.html">installed</a>
+ onto a disk image in GXemul. The device emulation of the DECstation
+/200 is reasonably complete; it should be enough to emulate a
+ networked X-windows-capable workstation.
+ <p>NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately,
+ newer NetBSD releases have changed slightly, and X does not work straight
+ away with NetBSD 2.x and 3.x. It seems that this has to do with NetBSD
+ switching console system to "WSCONS" somewhere between 1.6.2 and 2.0.
+ <p>What this means is that if you want to use emulated X11, then you need
+ to run NetBSD 1.6.2. At the time of writing this, 4.0_BETA snapshots work
+ fine too, but 4.0 isn't released yet. If you feel that you only need
+ serial-console emulation, then choose 3.1.

    <li>Create an empty harddisk image, which will be the root disk

  </pre>
- </ol>
- <p>
- From this point, there are two separate ways to continue the installation.
- You can either download a CD-ROM iso image (and let the installation
- program copy files from the CD-ROM image to the harddisk image), or you
- can install via ftp. For an installation from a CD-ROM image, follow these
- steps:

+         <li>When halting/rebooting NetBSD/netwinder, the emulator

+ <p>The general idea behind Linux/Malta seems to be that the end user

+ userland separately, etc. For that reason, Linux/Malta support in the
+ emulator is not tested for every release (sometimes it works, sometimes it
+ doesn't work), and these instructions are kind of "fuzzy".

- <p>It is tricky to install, because there is (as far as I know) no INSTALL

+ <h3>Linux/QEMU_MIPS:</h3>
+ I've added a machine mode which emulates the MIPS machine mode used
+ in Fabrice Bellard's <a href="http://fabrice.bellard.free.fr/qemu/">QEMU</a>.
+ Starting with QEMU 0.9.0, there are other MIPS modes in QEMU (i.e. Malta);
+ the QEMU_MIPS mode in GXemul refers to the old QEMU-specific MIPS machine.
+ <p>The following steps should let you boot into the Linux/QEMU_MIPS
+ kernel, in way similar to the <tt>run-qemu</tt> script:
  <p>
- The following instructions will let you install the NetBSD/netwinder
+ <ol>
- distribution onto a disk image, from an emulated DECstation 3MAX machine:
+   <li>Download the archive from
+         <a href="http://fabrice.bellard.free.fr/qemu/download.html">http://fabrice.bellard.free.fr/qemu/download.html</a> and extract it:<pre>
+         <b>wget <a href="http://fabrice.bellard.free.fr/qemu/mips-test-0.2.tar.gz">http://fabrice.bellard.free.fr/qemu/mips-test-0.2.tar.gz</a>
+         tar zxvf mips-test-0.2.tar.gz</b>
+ </pre>
+   <li>Start GXemul using the following command line:<pre>
+         <b>gxemul -E qemu_mips -x -M 128 -o 'console=ttyS0

+ <h3>Windows NT/MIPS:</h3>
+ Old versions of Windows NT could run on MIPS hardware, e.g.
+ the PICA 61. It is theoretically possible that the emulation provided by
+ GXemul some day could be stable/complete enough to emulate
+ such hardware well enough to fool Windows NT into thinking
+ that it is running on a real machine.
+ <font color="#ff0000">IT DOES <b>NOT</b> WORK YET!</font>
+ <p>Installation steps similar to these would be required to install
+ Windows NT onto a disk image:
+ <ol>
+         <li>Put a "Windows NT 4.0 for MIPS" CDROM (or similar) into
+                 your CDROM drive. (On FreeBSD systems, it is
+                 usually called <tt>/dev/cd0c</tt> or similar. Change
+                 that to whatever the CDROM is called on your system,
+                 or the name of a raw .iso image. I have tried this
+                 with the Swedish version, but it might work with
+                 other versions too.)
+         <p>
+         <li>Create an empty harddisk image, which will be the disk image
+                 that you will install Windows NT onto:<pre>
+         <b><tt>dd if=/dev/zero of=winnt_test.img bs=1024 count=1 seek=999000</tt></b>
+ </pre>
+         <li>Run the ARC installer, to partition the disk image:<pre>
+         <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\ARCINST</tt></b>
+ </pre>
+         Note that <tt>ARCINST</tt> <i>almost</i> works, but not quite.
+         <p>
+         <li>Run the SETUP program:<pre>
+         <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\SETUPLDR</tt></b>
+ </pre>
+ </ol>
+ <p><tt>SETUPLDR</tt> manages to load some drivers from the cdrom,
+ but then it crashes because of incomplete emulation of some hardware devices.
